Ok this question might shake a few tables and I'd really love it if some guys gave their own input.

In my opinion I believe that whoever did the asking out should pay the bill of the date and most times its the guy that asks the girl out so I guess the guy should be the one that spends more. If it's the girl that asked the guy out then she should be the one to pay for things on the date.

If bother parties agree to meet up somewhere and it was a mutual agreement then they should both split the bill. I don't believe that for every situation one person should pay the bill. It shouldn't be like that, but in the world we live in, for the most part, guys are the ones that make the first moved when it comes to dates and as such they should be the ones that pay.

Imagine a scenario where a girl doesn't want to go anywhere on a particular day, but then a guy asks her out on a date that same day. Not meaning to be rude, she agrees and decides to meet him somewhere, there's no reason why she should pay for anything seeing as she's only there because of the guy. The same thing goes for when a girl asks a guy out.

To answer your question, I believe that who ever initiated the idea of going on the date should spend more.
